- This invention relates to safety razors of the typein-'which athin,.leXible blade is clamped in operative position between cap andguard `members for shaving. In using razors of this type, theconvenience of the user requires that the blade-positioning andclampinor operations 'be quickly and conveniently effected and that thecap and guard may be as easily Separated to permit the removal yandreplacement of blades. My invention" contemplates a novel constructionof cap and guard so constructed and arranged that these operations maybe effected with an unusual degree of convenience and Without entirelydisconnecting the parts, thus avoiding the annoyance of loose partswhich may become misplaced and lost. VTothis end, an important featureof my invention comprises co-operating cap and guard members directlyinterconnected with each other byimeans of a connection which permitsthem` to be superposed in blade-clamping relation or `to be moved in apath at right anglesto each other for `the purpose of eX- posingtheblade-receiving face of one member.V

` There are many Ways in which the desired results may beachieved, butas herein shown, I provide an opening in the guard member of suchdimensions that the cap member may be tilted into angular position andpassed freely` therethrough. `In this way, the blade-receiving face ofthe guard may be fully exposed so that a blade may be pre sented andremoved bytheuser without obstruction of any kind.V By providing limitstopsat the opposite ends of the cap, the latteris prevented from beingentirely disengaged from fthe guard at any time. The cap ,is ,thusmaintained at all times within convenient reach of the user who is neverat a lossto determine its whereabouts. `The manipulation of the cap inthis manner, moreover, may be effected without danger of cuttingthefingers or damaging the sharp edges ofthe blade.

. I have referred to limit stops for preventing complete disengagementof the cap and guard. In accordance with another feature of theinvention, I may provide limit stops in the shape of projecting lugswhich havethe additional function of co-operating with recesses in theblade or in the guard to es-L tablish an accurate location of the capwith respect thereto-g or `the Vlimit stops may be Y posesofillustration and shown in the ac-` companying drawing, in which,-n

Fig. 5 is a similar view showing the'blade removed, and i F ig. 6 is aplan view ofa blade suitable for use;in arazor. 1

The razor shown in thedrawing comprises a cap member l() having a lower,concave, blade-shaping surface and parallel longitudinal edges adaptedto contact with the blade adjacent to its cutting edges. The `cap isprovided with a pair of recesses l2 in its blade-engaging face and witha centrally-disposed threaded hole 14. At one endof the cap is provideda pair of projecting lugs 16 and atthe other end a pair `of out-turnedhookslS. H

The guard member 20 of `therazor has a generally convex blade-shapingface havinvr formed therein a pair of parallel shoulderts? overwhichvthe blade is flexed when clamped 1n operative position. Along itsopposite edge, the guard member 20 is providedwith teeth Q2 as iscustomary in razors of this type. A pair of spaced, blade-locating studs24k proj ect from the blade-engaging face of the `guard and a pair ofrecesses 26 is provided at one end to receive the lugslof the cap withclearanceand so permit the latter to assume its proper relative positiontothe guard. At its other end, the guard is provided witha bail-shapedprojection 28 forming with the body of the guard a transverselyextendedpassage of such dimensions as to receive the cap 10 freely when thelatter is turned into a substantially upright position. as indicated indot-and-dash line in- Fig. 3. The rear end of the guard, or the innerwall of the opening formed by the bail 28, acts as a transverse fulcrumshoulder upon which the cap may be tilted from the horizontal positionshown in Fig. 2 to the vertical position shown in Fig. 3. The hooks 18project downwardly through the opening formed bythe bail 28 when the capis in its horizontal position and, when :the cap-is tilted, the hooks 18swing in under the guard. The shape of theopening formed by the bail 28is best shown in Figs. 4- and5, Fig. 5 showing also the iamount ofclearance aiiorded to the cap 10 when the latter isin its uprightposition.

. A f'blade 30, suitable for use in the illustrated razor, is shown inFig. 6 This is provided with oppositely disposed cutting edges 'andwith-corner recesses 32 designed to fitaccur-ate'ly upon the capvlugs16l and the hooks 18'. The blade is. also provided with anV.aperture 34 comprising :lan elongated slot fhavi-ng spacedenlargements shaped to fit upon the blade-locatingl studs 24 -of theguard and 'thus' accurately locate the blade in position when it ispresented thereto.

The-handleof the razor comprises a barrel 36 having a solid Vhead `whichis riveted or other-wisesecurely fastened to the guard 20. Within thebarrel 36 is freely received a stem38, threaded at, its upper end tolmake clamping engagement with the threaded hole 14 of the cap 10 andprovided at its lower end-with ta-knurled head 37 for convenience inmanipulation. VVithinthe-barrel 36 the stem-38is provided with a collar39 and the end `oftheibarrel 36 is flanged beneath this collar andbetween it andthe knurled head 37,"so that the stem is confined-tolimited longitudinal movement in the handle.f When disengagedfrom-itsthreaded connection withl thefcap 10,-'the1stem-38 is freetofdrop until its collar 391engages Ltheliangeat the lower end of thebarrel 36 vand in this movement the upperJendiof the-stem 38 is broughtHush with the blade-engaging face of the guard 20, as

v showniin-Fig. .3. Y

It iwillbe 'noted :that the parts of the razor herein disclosed areat-.alltimes connected so thatsin -usefthere @isf lnokdanger ofmisplacing-.loose parts. On theother. hand, the-construction .is such:that the .blade-receiving face of the guard 2O is; fully `exposedwithout obstructionv when .in `blade-receiving condition, the. 'cap.being entirely removed and droppedbelowtheblade-receiving face oftheguard. On `:theother hand, .the :cap may be easily .brought.intoblade-clamping position :andareadily clamped to establish the.shavin g relationship of the parts. With the razor in the conditionshown in Fig. 3, the blade may be conveniently placed by the user uponthe guard, being accurately and positively located by the studs 24 whichengage the enlargement inthe blade-locating aperture 34. The cap 10 maythen be brought-into its superposed, blade-clamping position by slippingit upwardlyv through the opening in the It will be understood that thebladeiis 14ar:-l

curately located upon the vguard member x20 by means of the studs 24',the outer ends whereof are received with clearance recesses 12 of thecapv member. The `cap member, onl the other hand is accurately locatedwith respect lto-the lblade 30 by -theiengagement of its lugs 164andhools 1f8 with the recesses 32 of the llatter and thus @properregistration and alignment ofthe whole assembly is insured.

Having-thus described my invention what I claim and ydesire to secure byLetters Patent of lthe'United States is: v
